The stainless steel throat hoop adopts an open inner and outer ring structure and is fastened with bolts. The American type hose hoop effectively solves the problems of dead angle and liquid and gas leakage when connecting small diameter soft and hard pipes, so it is widely used in the fixation of various water pipes, flexible pipes and other pipeline products. The exhaust pressure of stainless steel hose hoop is described in detail below.

The ratio of stainless steel hoop exhaust pressure and stainless steel hoop inlet pressure is called external pressure ratio. There are various internal resistances in stainless steel hoop, such as the pressure loss of stainless steel hoop inlet filter, the resistance loss of stainless steel hoop main engine inlet hole, the resistance loss of stainless steel hoop exhaust hole, and the resistance loss of stainless steel hoop oil subsystem When the pressure is lower than atmospheric pressure, the actual exhaust pressure of the stainless steel hose hoop is higher than the air supply pressure of the whole machine. The ratio of the actual exhaust pressure of the stainless steel hose hoop to the actual intake pressure of the main machine is called the internal pressure ratio. The closer the internal pressure ratio of the stainless steel hose hoop is, the more energy-saving the machine will be.

The low speed of stainless steel throat hoop makes its intake and exhaust orifice increase significantly, the air velocity at the orifice of stainless steel throat hoop decreases greatly, and the internal pressure ratio decreases, which leads to the reduction of energy consumption. In the process of compression, the input power of stainless steel throat hoop becomes heat, which makes the temperature of stainless steel throat hoop gas rise sharply. It needs to consume more power to compress high temperature gas with stainless steel throat hoop.

It takes time for the heat exchange between oil and gas in stainless steel throat hoop. The low speed of stainless steel throat hoop makes the heat exchange between oil and gas perfect. The temperature of stainless steel throat hoop rises slowly in the compression process and keeps low temperature all the time. Therefore, the power consumption in the compression process of stainless steel throat hoop is significantly lower than that of high speed stainless steel throat hoop, and the service life of lubricating oil in stainless steel throat hoop is also significantly prolonged.
